INSPECTION
HINT:
This check is used only to determine whether or not the idle CO/
HC complies with regulations.
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All accessories switched OFF
(e) All vacuum lines properly connected
HINT:
All vacuum hoses for EGR systems, etc. should be properly
connected.
(f) SFI system wiring connectors fully plugged
(g) Ignition timing check correctly
(h) Transmission in neutral position
(i) Tachometer and CO/HC meter calibrated by hand
2. START ENGINE
3. RACE ENGINE AT 2,500 RPM FOR APPROX. 180
SECONDS
4. INSERT CO/HC METER TESTING PROBE AT LEAST
40 cm (1.3 ft) INTO TAILPIPE DURING IDLING
5. IMMEDIATELY CHECK CO/HC CONCENTRATION
AT IDLE AND/OR 2,500 RPM
HINT:
When doing the 2 mode (idle and 2,500 rpm) test, these mea-
surement order prescribed by the applicable local regulations.

If the CO/HC concentration dose not comply with regulations,
troubleshoot in the order given below.
See the table below for possible causes, then inspect and cor-
rect the applicable causes if necessary.

VALVE CLEARANCE
INSPECTION
HINT:
Inspect and adjust the valve clearance when the engine is cold.
1. REMOVE RH FENDER APRON SEAL
2. DRAIN ENGINE COOLANT
3. REMOVE V±BANK COVER
(a) Using a 5 mm hexagon wrench, remove the 2 nuts.
(b) Disconnect the 2 clips, and remove the cover.
4. REMOVE HIGH±TENSION CODE SET
(See page IG±7)
5. REMOVE AIR INTAKE CHAMBER ASSEMBLY
(See page EM±32)
6. REMOVE IGNITION COILS
7. DISCONNECT RADIATOR HOSE FROM WATER
OUTLET
8. REMOVE CYLINDER HEAD COVERS
(See page EM±32)
9. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with the
timing mark º0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 (IN and EX) are
loose.
If not, turn the crankshaft 1 revolution (360°) and align the mark
as above.
10. INSPECT VALVE CLEARANCE
(a) Check only those valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record out of specification valve clearance mea-
surements. They will be used later to determine the
required replacement adjusting shim.
Valve clearance (Cold):
Intake0.15 ± 0.25 mm (0.006 ± 0.010 in.)
Exhaust0.25 ± 0.35 mm (0.010 ± 0.014 in.)

IGNITION TIMING
INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. CONNECT TOYOTA HAND±HELD TESTER OR
OBDII SCAN TOOL
(a) Connect a TOYOTA hand±held tester or OBDII scan tool
to the DLC3.
(b) Please refer to the TOYOTA hand±held tester or OBDII
scan tool operator's manual for further details.
3. CONNECT TIMING LIGHT TO ENGINE
Connect the tester probe of a timing light to the No.1 high±ten-
sion cord for No.4 cylinder.
4. CHECK IDLE SPEED
(a) Race the engine speed at 2,500 rpm for approx. 90 se-
conds.
(b) Check the idle speed.
Idle speed: 700 ± 50 rpm
5. INSPECT IGNITION TIMING
(a) Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843±18020
(b) Using a timing light, check the ignition timing.
Ignition timing: 8 ± 12° BTDC @ idle
(Transmission in neutral position)
(c) Remove the SST from the DLC1.

6. FURTHER CHECK IGNITION TIMING
Ignition timing: 7 ± 24° BTDC @ idle
(Transmission in neutral position)
HINT:
The timing mark moves in a range between 7° and 24°.
7. DISCONNECT TIMING LIGHT FROM ENGINE
8. DISCONNECT TOYOTA HAND±HELD TESTER OR
